House heater



Patented Mar. 5, 1935 UNITED STATES PATENT OFFICE 1,993,193 a V Y HOUSE HEATER. Harold H. Sykes, Grand Rapids, Application May 14, 1934', Serial No. 725,600 4 Claims. 401.126-90) This invention relates to a novel construction of heater which may be used by itself for the heating of air or, preferably, in conjunction with the usual construction of warm air furnace, such that a selected room or'part' of a house ordinarily supplied with heated air in severe cold weather by the furnace may be supplied with heated air from the heater during milder weather without the necessity of running the furnace. v The invention is for the purpose of producing an economically constructed and eflicient heater in which the fuel used may bea gaseousior liquid fuel, the burning of which heats 'air very quickly and efiiciently. 7

An understanding of the inventionand the ob jects and advantages thereof may be had from the following description, taken in connection with the accompanying drawing, in'which,

Fig. 1 is an elevation, with parts shown in section, illustrating the heater applied tothe warm air pipeof a furnace installation. Y 7

Fig. 2 is an enlarged verticalsection through the heater, and r Fig. 3 is a transverse section therethrough showing the heater radiator in plan.

In the construction of the heater (see Fig. 2), a base plate 1 of substantially circular outline is shown, at the center of which is an upwardly pro- J'ecting sleeve 2. Over this plate a radiator construction is located havingvertical walls 3 joined with a horizontal top 4, the middle portion of which is pressed upwardly into a dome 5 in the sides of which are a large number of outwardly pressed flutes 6. This provides an enclosure between the plate 1 and the radiator thereover. A

fiat baiile plate 7 is secured to and around the sleeve 2 and extends outwardly toward but stops a distance short of the walls 3. It is located be- 7 tween the base plate 1 and the top 4 of the radiator.

The plate 1 at one side of sleeve'2 has an opening 8 therein, connected with which is a sheet metal conduit member 9 which, with the plate 1 and an extension 1a thereof, provides a passage leading from the burner chamber underneath the radiator to an outlet pipe 10 which is secured at its lower end to the outer extension 1a of the bo tom plate 1. e

A cylindrical housing having vertical walls 11 and a top 12 is placed over the radiator and secured at its lower edge portions thereto. This housing has an inlet at 13 for the entrance of cold air.

An elongated somewhat enlarged cylindrical sleeve 14 passes downwardly through the top 12 plied with fuel through a pipe 17. The fuel may be any suitable fuel such as either a gaseous or liquid fuel which will burn readily. I

In operation of the burner as thus constructed,

it is evident that the heat from the burner'16will heat the radiating dome 5 and the fluted portions 6 thereof and also will heat the top 4, the products 'of combustion of the burning fuel necessarily flowing outwardly between the upper. side of. the baflle plate 7 and said top 4 ofthe radiator member, after, which the products of combustion :pass underneath the baflie plate and escape at the opening 8 through the conduit at'9 and thence to the outlet pipe 10; 1

Cold air entering thehousing 11 through the in-,- let at'1-3 passes downwardly and is heated by the radiator with heated airrising through the outlet 14. The arrows indicate the direction of flow of the cold air inwardlyat the inlet Band-outwardly through the sleeve 14. This heater may be used by itself for heating a room or other enclosed space. It is of simple economical structure, all parts thereof being made of sheet metal except the burner and the pipe 17 leading thereto. The radiator transmits the heat from the burner to the air quickly and efficiently. I

This heater is particularly adapted to be used in conjunction with the warm air pipe of a warm air furnace. In Fig. 1 it is shown installed on a furnace pipe. 7 The interior fuel burning struc- Y ture 18, consisting of firepot, combustion chamber and radiator, is enclosed within an outer casing 19 to which a cold air pipe 20 leads from a. register 21 installed in the floor 22 of a room. Cold air passing through this pipe to and inside the furnace casing 19 is heated and passes outwardly through a warm air pipe 23 to a warm air register 24 so that the warm air is directed into the room.

In a warm air furnace pipe, such as indicated at 23, a damper 25 is usually mounted, or may be mounted across the same for controlling, the amount of warm air which passes therethroug h. With my installation of the heater of my invention on the warm air pipe 23, the outlet 14 for heated air is connected to the pipe 23 between the damper and the register 24. The inlet at 13 for cold air is connected to the pipe 23 between the furnace casing and the damper 25 as shown in Fi 1.

With the damper 25 in a position to close the pipe 23, that is, transversely across the same, cold air passing through the cold air pipe 20 to the furnace casing 19 may thence pass out through the pipe 23 to the inlet 13 to the outer casing 11 of the heater. Such air is heated and then passes outwardly through the outlet 14 to the pipe 23 at the opposite side of the damper 25 and thence to the room through the register at 24.

' The products of combustion from the pipe may be led into the smoke pipeof the furnace.

Thisassembly, as shown in Fig. 1, provides a convenient way for heating a room normally supplied with hot air from the furnace through a furnace hot air pipe such as 23 at times when the weather is mild enough that the furnace asa whole should not be operated yeta limited amount of heat is desirable. Of course more than one of the outlet warm air pipes to the furnace may be supplied with the heatersas described. ;When the 1. A heater comprising, a horizontal base hav-' ing a central opening and an upwardly extending sleeve at said opening, a burner located in said sleeve, a'horizontal baffle'plate located" around the sleeve andspaced from said base, aradiator having an upwardly extending dome portion over said burner and with sides extending from said dome to the outer edge portions oiithe base to form a closed chamber, said base having an 'outlet opening and'a conduit connected therewith to carry away products of combustion, said baflle plate overlying the outlet opening in the base, an'dmeans for conducting heatedair away from the radiator; said means comprising a pipe, the
